Claper is an open-source audience engagement platform that makes presentations interactive with real-time participation. It helps speakers collect live feedback while giving attendees an easy way to ask questions and respond during talks.
Key Features
- Live audience interactions such as polls, quizzes, and Q&A during an event
- Real-time feedback to help presenters adapt content while speaking
- Event reporting and data exports for post-event review
- Team collaboration to manage presentations and events together
- Multi-language user interface (includes English, French, German, Spanish, Dutch, Italian, Hungarian, and Latvian)
Use Cases
- Classroom engagement with quick quizzes and anonymous questions
- Corporate meetings to gather input and validate decisions via instant polls
- Conferences and live events to run interactive sessions and collect feedback
Limitations and Considerations
- Some hosted-plan features and limits (such as attendee caps and presentation size) may differ from a self-managed deployment
Claper is well-suited for educators, teams, and event organizers who want a lightweight, real-time interaction layer for presentations. It provides core engagement workflows while remaining deployable on your own infrastructure.
